During the Phantom Troupe's attack on Zazan's colony, Boki manipulates another Chimera Ant soldier, Pell, into fighting Shalnark.[2] Confident that he won against Pell and is now under his control, Shalnark briefly lowers his guard and Pell restrains him. Boki reveals himself and that he was already manipulating Pell with his joystick controller. Boki then informs Shalnark that he'll put his own personal antenna onto Shalnark, deliver him to the Queen and his job will be complete.[1]

Boki obliterated by Shalnark

After a back and forth conversation on what will happen to Shalnark, when he becomes under Boki's control. Shalnark reveals that he has a second antenna on his person and uses it on himself to activate his Autopilot mode Nen ability. Anxious and overcome with fear, Boki tries to get Pell to remove the antenna from Shalnark's leg, however Shalnark breaks free from his restriction and obliterates both Pell and Boki in a single strike.[3]

Boki is a Manipulator. After sticking his antenna on his target, he can remotely control it as he pleases through a device that looks like a game joystick.[1] He might be able to control more than one target at once.
